c++语言实现的具体代码

以下是使用C++语言实现的具体代码：

#include <iostream>
#include <string>
using namespace std;

int findLongestOnes(string sequence) {
    int start = 0;
    int length = 0;
    int maxLength = 0;
    
    for (int i = 0; i < sequence.length(); i++) {
        if (sequence[i] == '1') {
            length++;
        } else {
            maxLength = max(maxLength, length);
            start = i + 1;
            length = 0;
        }
    }
    
    maxLength = max(maxLength, length);
    
    return maxLength;
}

int main() {
    string sequence;
    cout << "请输入长度为n的01串：";
    cin >> sequence;
    
    int longestOnes = findLongestOnes(sequence);
    
    cout << "最长连续1的区间长度为：" << longestOnes << endl;
    
    return 0;
}

你可以将上述代码保存为一个.cpp文件，然后编译运行即可。在运行时，程序会要求你输入一个长度为n的01串，然后输出最长连续1的区间长度。
